What is the sensor width of an iPhone 11? I need it for motion tracking
Found more specifications at https://www.gsmarena.com/apple_iphone_11-9848.php
The focal length for a wide video is 26mm, 1/2.55 sensor width and pixel size 1.4nm.
I have found: https://www.vision-doctor.com/en/camera-calculations/sensor-diagonal-sensor-ratio.html. I simply put in the video's pixel width and height (3840 x 2160) and the pixel size (1.4nm). It gave a more accurate sensor width than the preset in Blender: 5.38mm.
Hopefully, this helps someone.
